Abstract
Description
Technical Field
[0001] The utility model belongs to the field of manipulators, in particular to a sensor component of a manipulator of thermoforming equipment. Background Art
[0002] To improve production efficiency during the thermoforming process, a robotic gripper is required to pick up and unload workpieces after forming. The thermoforming equipment's robotic gripper is typically mounted on a movable base that reciprocates along guide rails. The gripper uses a pneumatic cylinder to pick up the workpiece and move it along the guide rails. Currently, photoelectric sensors are used to detect whether the workpiece is in place. However, these sensors are typically fixed in position, making them prone to misdetection when the robotic gripper moves. Utility Model Content
[0003] In view of this, the present invention aims to propose a sensor assembly for a thermoforming equipment robot, which is applicable to the thermoforming equipment robot, so as to more accurately monitor whether the formed workpiece is successfully sucked when the robot moves.

[0005] Compared with the prior art, the sensor assembly of a thermoforming equipment robot and the novel robot described in the present invention have the following advantages:
[0006] A sensor assembly for a thermoforming equipment robot is based on a robot arranged on the thermoforming equipment for sucking workpieces, the robot is connected to a robot arm, and the sensor assembly includes a sensor, a mounting plate, a sleeve, a first tightener, and a second tightener; the mounting plate is an overall rectangular plate, a sleeve is arranged on one side of the mounting plate, and a sensor is arranged on the other side of the mounting plate, the sensor is used to detect whether the robot has sucked the workpiece; the first tightener is mounted on the robot arm, the second tightener is mounted on the sleeve, and one side of the second tightener is connected to the side of the first tightener.
[0007] Furthermore, the mounting plate is provided with two screw holes, which are spaced apart from each other along the long side of the mounting plate. Screws are installed in the screw holes, and the sensor is mounted on the mounting plate by the screws to form a detachable connection.
[0008] Furthermore, the first tightening device includes two oppositely arranged arc-shaped first tightening members, the two first tightening members are equipped with the mechanical arms, and the two first tightening members are connected on both sides by a first fixing bolt and a first locking bolt respectively.

[0011] Furthermore, the sensor is a photoelectric sensor.
[0012] The sensor assembly described in the utility model is used to mount the sensor on the robot arm. When the robot arm moves, the sensor can move with the robot arm, and can more effectively detect whether the robot arm has successfully sucked the workpiece. This avoids the detection errors that are prone to occur with fixed sensors and improves the accuracy of detection. This solves the problem of detection errors that are prone to occur when the robot arm moves. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0021] like Figures 1 to 3As shown, a sensor assembly of a thermoforming equipment robot is based on a robot 2 for sucking a workpiece 4 arranged on the thermoforming equipment, the robot 2 is connected to a robot arm 1, and the sensor assembly 3 includes a sensor 10, a mounting plate 11, a sleeve 12, a first tightener and a second tightener; the mounting plate 11 is an overall rectangular plate, a sleeve 12 is provided on one side of the mounting plate 11, and a sensor 10 is provided on the other side of the mounting plate 11, and the sensor 10 is used to detect whether the robot 2 sucks the workpiece; a first tightener is mounted on the robot arm 1, a second tightener is mounted on the sleeve 12, and one side of the second tightener is connected to the side of the first tightener.
[0022] The utility model discloses a sensor component for a thermoforming equipment robot. A mounting plate is arranged on the robot arm through a first tightening device and a second tightening device that are connected to each other. The robot arm is equipped with the first tightening device, and the sleeve is equipped with the second tightening device. When the robot arm shaft moves, the sensor can move together with the robot arm, so that the sensor is installed on the robot arm for detection, which can effectively detect whether the workpiece after molding is successfully sucked. When the robot arm moves, the sensor component moves accordingly, thereby avoiding the situation where detection errors are likely to occur and improving the accuracy of detection.
[0023] like Figure 2 As shown, the mounting plate 11 has two screw holes 13 spaced apart along the long side of the mounting plate 11. Screws are installed in the screw holes 13, and the sensor 10 is removably attached to the mounting plate 11 via the screws. Specifically, the screw holes are tapped and then installed, and the internal and external threads mate to form a connection with the sensor. This stabilizes the sensor even under high vibration and high production frequency, allowing the sensor to be precisely connected and secured to the robotic arm.
[0024] like Figure 3 As shown, the first tightening device includes two oppositely arranged arc-shaped first tightening members 15, the two first tightening members 15 are equipped with the robotic arm 1, and the two first tightening members 15 are connected on both sides by a first fixing bolt 16 and a first locking bolt 14 respectively.
[0025] like Figure 3 As shown, the second tightening device includes two oppositely arranged arc-shaped second tightening members 18, the sleeves 12 are fitted inside the two second tightening members 18, and the two sides of the two second tightening members 18 are connected by a second fixing bolt 17 and a second locking bolt 19 respectively.
[0026] like Figure 3 As shown, the lower portion of the first fixing bolt 16 is connected to the second fixing bolt 17 .
[0027] The sensor is installed on the robot arm through the interconnected first tightener and the second tightener. When the robot arm moves, the sensor can move with the robot arm, and can more effectively detect whether the robot arm has successfully sucked the workpiece; improve the accuracy of detection; simplify the structure and reduce production costs.
[0028] The sensor 10 is a photoelectric sensor. The preferred model of the photoelectric sensor used in this embodiment is HLD-BS20-PS.
[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
